I'm trying to extend the life of my chicken coop and need to make the roof watertight. Does anyone know if silicon sealant is safe for chooks? (The sort you put around the bath or the kitchen sink). I'll be putting it along the roof plank joints, inside and out - it'll be about 80cm above the roosting perches, but only 30 cm above the nesting box straw. I don't want to use anything that may cause them harm.
Thanks
